The Metl-Span CF Mesa and Light Mesa insulated metal wall panels are well suited for exterior and interior partition wall applications. The lightly corrugated profile on both faces of the panels ensures symmetry from outside of the building to inside, and from room to room in partition installations. The CF Mesa and Light Mesa wall panels may be used for exterior wall applications, but they are not recommended for use on exterior walls of low temperature buildings.

Star Shield
Metl-Span profiled panels with a urethane foam core have a standard FM Class 1 approval and offer the best insulating values available today.

Panels are lightweight and quick to install, significantly reducing construction time.

A double tongue-and-groove offset side joint permits concealed fastening.

Consistent insulating values are achieved with built-in thermal breaks, saving energy.

The metal and foam composite construction creates a rigid panel far stronger than the individual parts. This increases the span capability of the panels and reduces the need for secondary structural steel components.

Properties Notes:

  1. All calculations for the properties of BattenLok HS® panels are calculated in accordance with the 2001 edition of the North American Specification For Design Of Cold-Formed Steel Structural Members.
  2. Ixe is for deflection determination.
  3. Sxe is for bending.
  4. Maxo is allowable bending moment.
  5. All values are for one foot of panel width.


Allowable Uniform Loads Notes:

  1. Allowable loads are based on uniform span lengths and Fy = 50 ksi.
  2. LIVE LOAD is limited by bending, shear, combined shear and bending and web crippling.
  3. Allowable loads consider a maximum deflection ratio of L/180.
  4. The weight of the panel has not been deducted from the allowable loads.
  5. THE ALLOWABLE UNIFORM LOADS ARE NOT FOR USE WHEN DESIGNING PANELS TO RESIST WIND UPLIFT.
  6. Please contact manufacturer or manufacturer's website for most current allowable wind uplift loads.
  7. The use of any field seaming machine other than that provided by the manufacturer may damage the panels, void all warranties and will void all engineering data.

  • Based on CF-30, CF-36 and CF-42 panel with 26 ga. Mesa exterior & interior faces (min Fy = 33 ksi).
  • For pattern FP1, CF panel clips are fastened to minimum 14 gage steel with (2) 1/4"-14 SDS Tek 3 at interior supports and (1) 1/4"-14 SDS Tek 3 at end supports.  For 12 gage or thicker steel, #12-24 SDS or 1/4-14 SDS Tek 5's may be used.  In lieu of self-drilling screws, self-tapping screws may be used.
  • Fastening patterns FP2, FP3, FP4 and FP5, includes CF panel clip attachment plus 1, 2, 3 or 4 Fabloks, respectively, at supports per panel width.  Fab-lok spacing is 10.5" OC from female edge of panel seam.
  • The through fasteners (FP9) are as follows:  #12-24 SDS in min 12 ga. steel; or #1/4-14 SDS in min 12 ga. steel; or #1/4-14 STS in min 14 ga. steel.  4 Fasteners with 5/8" neoprene bonded washers per panel width @ max 8.4" OC.
  • The through fasteners (FP10) are as follows:  #12-24 SDS in min 12 ga. steel; or #1/4-14 SDS in min 12 ga. steel; or #1/4-14 STS in min 14 ga. steel.  5 Fasteners with 5/8" neoprene bonded washers per panel width @ max 8.4" OC.
  • Allowable suction load is the lowest value of panel bending strength, shear strength, deflection limit and connection strength for each fastening pattern.
  • Allowable loads based on panel stress and deflection design criteria are derived from ASTM E72 structural testing and calculated with factor of safety of 2.5 for bending stress, 3.0 for shear stresses and deflection limitation of L/180.
  • The panel connection strength was determined from ASTM E1592 testing and the allowable loads are calculated with factor of safety of 2.
  • Consult Metl-Span for recommendations on panel profile and gage suitable for thermal stresses.

  • Based on CF-30, CF-36 and CF-42 panel with 26 ga. Mesa exterior & 26 ga. Mesa interior faces (min Fy=33 ksi).
  • Refer to the allowable connection load chart, for suction loads, which controls support spacing requirements.
  • Allowable positive load is the lowest value of panel bending strength, shear strength & deflection limit.
  • Allowable loads based on panel stress and deflection design criteria are derived from ASTM E72 structural testing and calculated with factor of safety of 2.5 for bending stress, 3.0 for shear stresses and deflection limitation of L/180.
  • The structural capacity of the girts are not considered and must be examined independently.
  • Consult Metl-Span for recommendations on panel profile and gage suitable for thermal stresses.

  • Based on CF-30, CF-36 and CF-42 panel with 26 ga. Light Mesa exterior & interior faces (min Fy=33 ksi).
  • For pattern FP1, CF panel clips are fastened to minimum 14 gage steel with (2) 1/4"-14 SDS Tek 3 at interior supports and (1) 1/4"-14 SDS Tek 3 at end supports.  For 12 gage or thicker steel, #12-24 SDS or 1/4"-14 SDS Tek 5's may be used.  In lieu of self-drilling screws, self-tapping screws may be used.
  • Fastening patterns FP2, FP3, FP4 and FP5, includes CF panel clip attachment plus 1, 2, 3 or 4 Fabloks, respectively, at supports per panel width.  Fab-lok spacing is 10.5" OC from female edge of panel seam.
  • The through fasteners (FP9) are as follows:  #12-24 SDS in min 12 ga. steel; or #1/4-14 SDS in min 12 ga. steel; or #1/4-14 STS in min 14 ga. steel.  4 Fasteners with 5/8" neoprene bonded washers per panel width @ max 8.4" OC.
  • The through fasteners (FP10) are as follows:  #12-24 SDS in min 12 ga. steel; or #1/4-14 SDS in min 12 ga. steel; or #1/4-14 STS in min 14 ga. steel.  5 Fasteners with 5/8" neoprene bonded washers per panel width @ max 8.4" OC.
  • Allowable suction load is the lowest value of panel bending strength, shear strength, deflection limit and connection strength for each fastening pattern.
  • Allowable loads based on panel stress and deflection design criteria are derived from ASTM E72 structural testing and calculated with factor of safety of 2.5 for bending stress, 3.0 for shear stresses and deflection limitation of L/180.
  • The panel connection strength was determined from ASTM E1592 testing and the allowable loads are calculated with factor of safety of 2.
  • The structural capacity of the girts are not considered and must be examined independently.
  • Consult Metl-Span for recommendations on panel profile and gage suitable for thermal stresses.

  • Based on CF-30, CF-36 and CF-42 panel with 26 ga. Light Mesa exterior & 26 ga. Light Mesa interior faces (min Fy=33 ksi).
  • Refer to the allowable connection load chart, for suction loads, which controls support spacing requirements.
  • Allowable positive load is the lowest value of panel bending strength, shear strength & deflection limit.
  • Allowable loads based on panel stress and deflection design criteria are derived from ASTM E72 structural testing and calculated with factor of safety of 2.5 for bending stress, 3.0 for shear stresses and deflection limitation of L/180.
  • The structural capacity of the girts are not considered and must be examined independently.
  • Consult Metl-Span for recommendations on panel profile and gage suitable for thermal stresses.

  • Based on panels with 26 gage exterior and 26 gage interior face (min Fy = 33 ksi) for single span condition.
  • Allowable span is the lowest value of panel bending strength, shear strength and deflection limit.
  • The spans based on panel stress and deflection design criteria are derived from E-72 structural testing.
    The allowable loads are calculated with a factor of safety of 2.5 and 3.0 for bending and shear stresses, respectively
    and deflection limitation of L/120.
  • The structural capacity of support members and panel attachment to the support members are not considered
    and must be examined independently.
IMPORTANT NOTES:
Deflection caused by temperature differential induced thermal bow is not addressed in the above table and may result in allowable spans that are less than the spans listed above and may require the use of heavier 24 or 22 gage panel facings at added cost. Except for self-supporting the dead weight of the panel, partition wall panels are non-load bearing. Ceiling panels must be supported from the structure above or by an internal support structure. Panel skins must be captured at both ends of the panel by supporting members designed to support reaction pressures from a 5 psf interior pressure. CF-42 = 42" wide. CF-45 = 44.5" wide.
